This unit was organized in December of 2005 and currently has one K-9 team that consists of Cpl. Erik Peterson and his partner K-9 "ROCK".

K-9 handler, Cpl. Peterson has been in law enforcement since December of 1998 after serving active duty infantry with the United States Marine Corps. During Cpl. Peterson's time in law enforcement he has served as both a Drug Task Force investigator and as a uniformed patrol deputy before starting the Sheriff's Office K-9 program.

His partner K-9 Rock is a German Sheppard who was imported from Hungary to the Castle K-9 training grounds in Mechanicsburg Pennsylvania. The K-9 team responded for a live-in training academy at Castle K-9 where they were nationally certified as a patrol/narcotics K-9 team.

The purpose of the K-9 Unit is to provide the citizens of Caroline County with a trained police service dog to help locate illegal narcotics, apprehend violent offenders, locate discarded/hidden evidence, track fleeing suspects, and to find lost or missing persons. The K-9 team has proven on numerous occasions to be an asset to the Caroline County Sheriff's Office, the Drug Task Force, Caroline County's municipal police agencies, and the communities themselves. On an average the K-9 team is directly involved in over 100 illegal drugs and/or criminal apprehensions per year, along with seizing large amounts of narcotics, guns, drug money, and property from violators of Maryland's drug laws.

The K-9 team not only supports Caroline County, but numerous surrounding counties as well. The K-9 team is funded by seized funds through investigations initiated by the Caroline County Drug Task Force. The K-9 team must be continuously trained and certified yearly in its particular duties. As officers must be trained in law enforcement, so must police dogs. Most of the training is conducted by the handler on a daily basis, although numerous training hours are put in both with the surrounding agencies K-9 Units, and certified master trainers. Whether it be removing drugs and drug money from the hands of drug dealers, apprehending violent felons, or returning a lost family member to his/her loved ones, the Caroline County Sheriff's Office's K-9 Unit is always ready.
